UK's Indivior shares tumble on lower 2025 revenue forecast

(Reuters) -British drugmaker Indivior on Thursday projected a 17% fall in 2025 net revenue at the midpoint of its forecast range, partly hurt by weak sales of its film-form medication-assisted therapy for opiate addiction, sending its shares sharply lower.

Shares in the company fell as much as 22.8% to a near four-month low of 670.5 pence in early trade.

CEO Mark Crossley said the steep fall expected in 2025 net revenue was primarily due to a more than 50% drop at its opiate addiction therapy, Suboxone film, amid intense generic pricing pressures and the potential entry of a fifth generic competitor.

In October last year, Indivior issued its second profit and revenue warning in three months citing weak sales of its opioid addiction treatment Sublocade due to competition from Swedish pharmaceutical firm Camurus' drug Brixadi.

Indivior, which has a market value of just over 1 billion pounds ($1.26 billion), reported a 16% rise in adjusted operating profit to $312 million for the year ended December 31, 2024.

After a 9% increase in net revenue to $1.19 billion last year, the company expects between $955 million and $1.03 billion for 2025.
